Given numbers are 399, 190, 985, 669
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 190) = 3990
GCD(399, 190) = ( 399 x 190 ) / 3990
= 399 / 190
= 399
Step2:
LCM(19, 985) = 18715
GCD(19, 985) = ( 19 x 985 ) / 18715
= 19 / 985
= 19
Step3:
LCM(1, 669) = 669
GCD(1, 669) = ( 1 x 669 ) / 669
= 1 / 669
= 1
So, Greatest Common Divisor of 399, 190, 985, 669 is 1
